Insights
How these are computed- Run-rate, measured
- pending
- Needs two observations at least 14 days apart. Our next read of this page turns this on. Nothing is extrapolated from a single contract.
- Lifetime pace
- $5.5K/yr estimate
- Lifetime earnings divided by years on Upwork. A floor on historical pace, not a forecast.
- Earnings per job
- $675
- Average contract value to date.
- Recent earnings, per Upwork
- $2.3K
- The "recent" figure Upwork attaches to the directory card, with 197 recent hours. Upwork does not publish the window, so it is shown as its number, not ours.
- Realised hourly
- $21/hr
- Total earned over billed hours. Fixed-price work inflates it; compare with the rate card.
